About the high temperature resistance quality of color steel coils

About the high temperature resistance quality of color steel coils

Color steel coil is a new type of material produced in China due to high-end applications in recent years, and is commonly referred to as CCLI. It is made of galvanized steel plate (55% aluminum, 43% zinc and 1.6% silicon) with more corrosion resistance than zinc as the substrate. After surface degreasing, phosphating, and complex acid treatment, it is coated with organic paint and baked. Color difference MAX.2.

Color-coated rolls can effectively save energy

Color-coated coils have good coloring, formability, corrosion resistance and decorative properties of organic compounds, as well as high strength and easy processing properties of steel plates. They are deep-processed products in the iron and steel industry and high-efficiency and energy-saving steels. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic paint are applied to the surface, and then baked and cured.

What are the requirements for the treatment of color-coated boards?

Through the recent survey and return visit to customers, we found that many customers do not understand the treatment of color-coated boards, and hope that manufacturers can further explain. Today, the editor will share the relevant information with you, hoping to inspire and help you. Processing requirements for color-coated boards?

The thickness of the color steel coil is very important

Color steel coil materials are divided into five categories: packaging, home appliances, building materials, optical materials and decorative materials. Among them, the color steel materials for home appliances have fine craftsmanship and high production requirements. The thickness of the substrate and peritoneal coating, the better color steel plate substrate is 0.02~ 0.05mm, and the thickness of the coating or coating is often only 0.15mm.

On the properties of easy forming of color steel coils

The coil light retention rate of color steel is more than 90%. The above data shows that aluminized zinc-plated color-coated sheets (AZ150, G345A, PVDF) are very suitable for buildings or other facilities in the environment, with corrosion resistance and climate resistance, and such steel sheets can be guaranteed by major steel mills. The service life of more than 20 years. Products made by baking with organic paint. Both steel plate and organic materials are a bit.

The difference between color coated plate and color steel plate

The difference between color coated plate and color steel plate

Color coated steel plate is made of cold-rolled steel plate and galvanized steel plate as the substrate, after surface pretreatment (degreasing, cleaning, chemical conversion treatment), coating with paint in a continuous method (roller coating method), baking and cooling. The product. Color steel plate refers to color-coated steel plate, which is a steel plate with organic coating. Color steel plate is divided into single plate, color steel composite plate, floor deck and so on. The specific differences are as follows: 1. During the refining process, the base plate of the color-coated plate is a steel strip used for coating paint. The treatment of the front and back of the color-coated plate is extremely important. Usually, the color, coating performance and surface High quality requirements. The color-coated plate has strong hardness and flexibility. Its coating resists mechanical effects such as scratches, friction, collision, and press-in. The coating of the color-coated plate and the substrate are deformed together without damage. . Color-coated boards start from the end of production, when the performance of the original coating drops to the interval that must be overhauled to maintain its protective effect on the substrate. Under the influence of use and over time, it will gradually age, so a major repair must be carried out to make its durability longer. 2. The color steel plate is a cold-rolled steel plate as the base material. After degreasing and phosphating treatment, double-sided hot-dip galvanizing is performed under the protection of nitrogen. After applying a chemical conversion film that is easy to adhere to the primer, Painted with epoxy resin primer and painted with chemical-resistant color topcoat to shape him. The color plate is a colored steel plate, which is coated with a layer of polymer material on the steel plate. There are single-sided and double-sided. Most of them are single-sided, and the surface can also be printed with patterns. The above two major points are the difference between color-coated plates and color steel plates that we often understand. When we choose to use, we must choose the products we need according to our actual situation. If you have any needs, you can contact us at any time.
